DUMP-CAR CONSTRUCTION.

Application led October 4,

The present invention relates to dump car construction. n v

In the type ofdump car known as ballast car the parts are commonly arranged so that lading may be dumped either centrally of the tracks upon which the car is mounted or outside of said tracks. As ordinarily constructed, ballast cars are so arranged as to dump only between the trucks so that the lading in being dumped between the tracks will not interfere with said tracks. In ordinary constructions, a considerable proportion of the length of the car has been unused. When the ballast car is used for carrying coal or other lading' which need not be dumped centrally of the track, ballast cars as ordinarily constructed donot have the maximum capacity which could be had within the over-all dimensions of the car.

An object of the present invention is to provide a railway dump car which combines the essential characteristics of a ballast car for selective side or center dumping with maximum carrying capacity for lading which vneed not` be dumped between the tracks.

A further object is to provide a car having the advantages of selective side or center dumping between the trucks together with side dumping over and beyond the trucks.

A. further object isto provide a modification of a well known type of selective dumping ballast car which ywill materially increase the capacity of said car for the carrying of lading which need not be centrally y dumped.

' Further objects will appear as the description proceeds.

Referring to the drawings:

Figure 1 is a view in side elevation of one embodiment of the present invention;

Figure 2 is a sectional view taken along the plane indicated by the arrows 2 2 of Figure 1; and

Figure 3 is a sectional view taken along the plane indicated by the arrows 3 8 ofy Figure 1. f

The numeral 1 indicates a car, only one end portion of said car being illustrated. Said car is provided with trucks at the two ends thereof, one of said trucks being indi-f' cated diagrammatically by the wheels 2, 2

tions 9, 9, attached to theV center sill 10; the

shedding cope 11 forming part of the center sill 10; and the sloping walls 12, 12, which deflect lading passing the doors 7, 7,'to a position intermediateof the track upon which thel wheels 2, 2 are mounted. n

vThe doors 7, 7 are controlled byoperating mechanism 13 which in turn is controlled by Vthe shaft 14. The doors 5, 5 are controlled by the longitudinally extending shafts 15, 15. f f v Ballast cars for dumping lading between the trucks are ordinarily provided withsloping end walls 16, of which one is illustrated Said sloping mechanism 3. According to the present invention, the sloping 'wall 16 instead of extending to the top of wall 1 near the end of the car, extends only to a line located above the corresponding truck and spacedl materially from the end of the car. A vertical wall 17 indicated in dotted lines in Figure 1, is provided whereby to form with the side walls 1, 1 and end wall 17of the car a receptacle 18 for such lading as coal, which need not be dumped centrally of the tracks. Each vertical wall 17 forms withits corresponding sloping wall 16 a structure triangular in cross section viewed transversely of the car, as shown in Figure 1.`

Each receptacle 18 is provided with the sloping bottom lwalls 19, 19, as illustrated in Figure 3. Said sloping walls 19, 19 have a meeting edge disposed medially of the car whereby lading within said receptacle is directed wholly to the sides of the car. lThe numerals 20, 2O indicate swinging doors pivoted for movement about the axes 21, 21.

In Figure 3 the right-hand door 2O is shown in closed position and the left-hand door is shown in open position. rhe operating mechanism for controlling the doors 20, 2O is not illnstrated" inasmuch as said operating mechanism does not constitute anyV part of the present invention. Various types of door operating mechanismI for dump cars are well known to those skilled in the art and no difliculties will be encountered'by theskilled artisan in adapting any of the well known door operatingVr mechanisms to' thedoors 20,20. y

It willbe clearfromthe' drawings'and the description above, that the present' invention provides a construction whereby the ad'- vantages of the selective dumping ballast car are retained ina constructionot: dump car having increased capacityy for material which need not bel directed between the tracks upon which the car is located. lhen the-car is being used for ballast', said ballast may be selectively dumped' between vthe tracks by operation of the doors .7', 7, or outside ot the tracks by opera-tion of'the doors 5,.5the ballast being directed towards said doors by means of the sloping walls 16 located near the ends of the car over the trucks. When, it is desired to use the car for the carrying of coal or other lading which need not be deposited between the tracks, not only is the center portion of the car utilized, but the end-` receptacles 18' are utilized as well', the lading within said receptacles 1S being dumpedoutside thevtraclts j past the doors 20, 20. By reason of the construction illustrated allot the capacity within theover-all dimensions of the car is utilized with the exception of the smallportion of triangular cross-section between the sloping end wall 16 andthe vertical wall 17- over each truck.

rllhough a preferred embodiment of the present invention has been described in detailit will be clear that many modi'cations will occur toy thoseskilled in the art-,which modilications will. not depart from the invention. It isintended to cover all' such modifications whichfall within the-scope of the appended claims,

l/Vhat is claimed is:

1. A dump cark hav-ing trucks,` a dump mechanism between saidtrucks for delivering lading either centrally of' or outside of the` tracks. upon which ,the car isu mounted, vertical walls forming with the end; and side walls of said car, a receptacle at each end ofV said car over said trucks, inclined walls associated with said verticalwalls for directing lading to the dump Imechanism between the trucks,v d'ump mechanisnn located adjacent to the ends ofsaid car for delivering lading from said receptacles toI regions out-sidey of said tracks, and sloping walls,l

mounted adjacent to said vertical walls, disposed transversely of said car and having their upper edges substantially coincident with said vertical walls, said sloping walls being disposed in positions to shed lading toward the dump mechanism located between said' truc'ks.

2. A ballast car having trucks, dump meansfor depositing lading selectively between or outside of the tracks upon which saidcanismounted, said dump means being located between said trucks, and sloping walls-above said-'trucks for shedding lading to said dump means, said ballast car being provided" with receptacles at the ends thereof, said receptacles being provided with dumping` mechanism for delivering lading at the side of' said tracks, each otsaid slopingwalls extending'to a line disposed transverselyfof said'car, which'line liesmaterially above the bottomk of the corresponding'receptacle and materially above said dumpmean's, whereby the correspondingslopingiwall forms an'. efficient dividing means` between; ladingintended to be directed betweenthe trucks' and lading in the corresponding receptacle.;

3. In combination, in a ballastl car, side walls, trucks locatedat the endsof said car, sloping walls extending over saidltrucks and selective dumping mechanisml located between said walls for deliveringlading` either centrally of or outside of the tracks. upon which said car is mounted, ysaid car having adjacent to each end thereof' a vertical wall connecting with a corresponding sloping bottom wall and forming with an end and side walls of' said car a receptacle for the reception of lading, and dump mechanism` f'or depositing lading from said receptacle to regions outside of said track.

4t. A dump car comprising side walls, a truck at each end ofl saidcar, slopingjwalls converging towardfthe transverse centerline of said'car and located in a position. above said trucks, a center sill extending longitudinally of. saidcar, selective' diimpingmechanism located between said sloping walls and below said center sillfor selectively delivering lading` inside of or outside of the tracks upon which the car is mountedQsaid car having a receptacle at each end," said receptacle having sloping` bottom walls located above said center sill` for deliveringy lading outside of" said tracks, each. of'said first mentioned sloping walls extendingjto` a line disposed transversely ofA said car, which line lies materially above the bottorn of the corresponding receptaclel and materially aboveY said selective dumping mechanism, whereby the corresponding sloping wall forms an eflicient dividing means between lading intended to be directed between the trucks and lading in the c'orrespondin'greceptacle. n

5. A dump` ca-r having trucks, a. diimp mechanism between saidy trucksfor delivering lading either centrally of or outside of the tracks upon Which the car is mounted, vertical Walls forming with the end and side Walls of said car, a receptacle at each end of said car over said trucks, inclined Walls associated With said Vertical Walls for directing lading to the dump mechanism bedeliveringv lading from said receptacles tor regions outside of said tracks.
